[0002] A DC charging pile is a charging device that is connected to the power grid and provides DC power to electric vehicle batteries. It can directly charge the batteries of electric vehicles. DC charging piles can be classified based on different dimensions such as power size, number of charging guns, structural form, and installation method. Among them, the more mainstream classification by structural form is to divide DC charging piles into two types: integrated DC charging piles and split DC charging piles.

[0003] The DC charging gun is an important component of the DC charging pile. It is used to connect electric vehicles and DC charging piles to provide DC power for charging electric vehicles. However, the current range of vehicles that can be charged by existing DC charging guns is relatively small. When charging piles cannot be set up in some places where there are no pillars, vehicles parked far away cannot be charged in time, affecting the efficiency of the use of the charging gun.
